New triple-decker complexes prepared by the stacking reactions of cationic metallofragments with sandwich compounds

The results of our recent studies devoted to the synthesis of cationic triple-decker complexes are summarized. The stacking reactions of cationic metallofragments with sand-with compounds can be used as a general method for the synthesis of these complexes. This method was used for the preparation of 30- and 34-electron cationic triple-decker complexes containing cyclopentadienyl and pentaphospholyl ligands in the bridging position and carbocycles C _n H _n (n=4–7) and carboranes as terminal ligands.
